r9982:

Removed project HeuristicLab.Problems.Instances.TestFunctions and integrated it into HeuristicLab.Problems.TestFunctions
Removed SOTFData from HeuristicLab.Problems.Instances and integrated it into HeuristicLab.Problems.TestFunctions
Changed SOTFData's Evaluator property to be of type ISingleObjectiveTestFunctionProblemEvaluator
Removed cast in the problem's load method

I think that in contrast to other problem instances this one is a bit special. Since we're using the plugin infrastructure's type discovery anyway there's no need to provide a generic format such as SOTFData in Problems.Instances to which other instance providers contribute. I felt it was not really right to have SOTFData use IOperator as the Evaluator property and then cast it to ISingleObjective...Evaluator in the load method. The load would always fail if the given operator was not an evaluator. I suspect IOperator was used because otherwise there is a circular reference between Problems.Instances and Problems.TestFunctions. I think the better solution in this case is to directly integrate the instance providing classes into the problem plugin. Any other instance provider would always need to reference the SOTF problem plugin anyway.
